Abstract: A modelling study was completed to assess the relative energy efficiency of ANSI/ASHRAE/IESNA Standard 90.1 (ASHRAE 90.1) and the National Energy Code of Canada for Buildings (NECB) for British Columbia (BC). This involved applying the prescriptive requirements for ASHRAE 90.1-2010 and 2016, and the NECB 2011, 2015 and 2017 to eight archetype models across three main regions, representing the large majority of the BC commercial market. Of these Standards, the NECB 2017 proved the most efficient based on energy use across the overall Part 3 BC market. All versions of the NECB provided for higher green¬house gas savings than any version of ASHRAE 90.1 in BC. However, ASHRAE 90.1-2016 had the highest savings based on energy costs.
